THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 414,946, dated November 12, 1889.

Application filed September '7, 1889. Serial No. 323,263. (No model.)

To all whom it may concern.-

Be it known that we, OTHO J. HOLTZMAN, of Boonsborough, NVa-shington county, and THOMAS FORSYTH, of Howardville, Baltimore county, Maryland, both citizens of the United States, have invented certain new and useful Improvements in Thin-Couplings, of which the following is a specification. Our invention relates to a device for coup- Io ling shafts and poles to the axles of vehicles,

and is illustrated in the accompanyingdrawings, in which Figure 1 is a section of the axle and a side view of the coupling. Fig. 2 is a top view of the same.

and that part of the coupling which is permanently attached to the axle-clip. Figs. 4, 5, and (3 show front, side, and section views, respectively, of the detachable ears of the coup- 2o ling. Fig 7 is a view of the spring.

The iron A of the shaft has the usual eye b, and fits bet-ween ears 0, where it is held by a bolt or pin (1. Thus the said iron is jointed so that the shaft may'have a vertical up-and- 2 5 down hinging movement. These ears are integral with a block 0, and constitute a separate and detachable part of the coupling. The ear-block is preferably tapering on two sides 6 in a vertical direction, as shown in Fig. 4, being broader across the top and narrower at the bottom. At the front, adjoining each side 6, is a holding-edge f. The block 0' has arecess g between the ears, and a rubber cushion g occupies the recess. This cushion acts on the eye-pieoeb of the thilliron and prevents it from rattling.

The axle-clip H has a holder for the earblock C. The said holder comprises two rigid side jaws I, which are slightly inclined,

as seen in Fig. 3, to correspond with the tapering sides 6 of the ear-block. The lower or bottom end of said two jaws are closer together than the top. Each jaw has a vertical inturned flange f, which takes over on the holding-edge f at each side of the ear-block Fig. 3 is a front view of'an axle and confines the latter. By this construction the ear-block may be placed into the holder by entering the block at the top of the holder and sliding it down until it becomes tight between the jaws. Any suitable means may be employed to confine the earblock in the holder. In the present instance two springs J are employed, each having a shoulder or side lug it. Each spring is attached to a side of the ear-block and fits in a vertical groove Z on the side, so as to permit the lower end of the spring to yield. It will be seen that when the lowerends of the two springs are compressed in a direction toward each other the shoulders 1.: of the springs will disengage from the lower edge of the rigid jaws I, and then the ear-block may be lifted out or detached from the holder. WVhen said springs expand in a direction away from each other, then the shoulders 7.: will engage below the jaws, and thereby the ear-block will be confined to its place on the holder.

Asshown in the drawings, the two springs .I are made of one iece of spring-steel bent into inverted-U shape, as in Fig. 7, and these inverted springs are attached to the ear-block.

At the side of each jaw I is a brace-piece m, to prevent the jaw from bending laterally.

In detaching a pair of shafts from a vehicleaxle the ear-block C will adhere or remain fast to the eyepiece b of the shaft-iron, because the pin d connects said parts. These may be separated by pushing the pin out. 0f 7 course it is impossible for the pin to accidentally come out when the ear-block is in the holder.

Having described our invention, We claim 1. The combination, in a thill-coupling, of the holder having side jaws I, the block 0, provided with inclined ears 0, and the iron A, having an eye 17 fitting between the ears 0 of the block 0, substantially as specified.

2. The combination, with the block 0', having inclined ears 0 and a recess g, provided with a cushion g, of theiron A, having an eye Z), which bears against said cushion, In testimony whereof we afix oursignatures whereby the rattling of the parts is prevented, in the presence of two Witnesses. substantially as specified.

3. The combination, in a thi1l-eoup1ing, of r his v 5 the iron A, proyided with an eye I), a de OHIO 32 3 {0L1 iachable block 0', having two inclined ears MAS FORSYTII,

a pin d, which fastens the eye to the earbloek, and. the springs J, whereby the ear- \Vitnesses: block is confined to the holder, substantially A. O. BABENDREIER,
